A few days ago, the American "Proceedings of the Electrochemical Society" published an article pointing out that whether it is a battery pack driven pure electric vehicle or a fuel cell electric vehicle, there are cost and durability challenges
.
Lithium/air or lithium/oxygen battery systems based on lithium currently lack stable electrode assemblies and electrolyte materials, and cannot guarantee that the regeneration and reduction rate of oxygen during the charge-discharge cycle reaches 100%.
Therefore, in the future basic research and material development, the feasibility of lithium/oxygen batteries should be further verified
.
It is difficult to obtain the ideal specific gravity energy density for lithium/sulfur battery packs, and the specific volumetric energy density achievable by lithium/sulfur battery packs is significantly lower than that of traditional lithium-ion battery packs
, regardless of the electrode material used.
In terms of specific volumetric energy density, lithium/sulfur battery pack cells are completely inferior to traditional lithium battery packs
.
However, considering the cost factor, lithium/sulfur battery packs may have certain advantages, as the price of additional components (diffusion films, etc.
) that improve life cycle and safety is relatively low
.
Silicon anodes for lithium/sulfur battery packs remain an open question of compatibility with lithium, including by pre-treating lithiumation processes in an industrially viable manner, or by replacing the sulfur cathode
with lithium sulfide.
In the past decade, hydrogen fuel cells have made great progress
.
The challenge now is to combine advanced catalyst concepts with highly durable carrier materials to ensure fuel cell performance over the entire life of the vehicle
.
The main challenge for fuel cell dielectrics is to discover materials suitable for high operating temperatures and relatively low humidity environments to help simplify system design, improve heat rejection efficiency, and reduce energy losses
in air compressors.
